  1. 清洁水泵轴 (6) 和壳体 (1) 中唇形密封 (9) 的沉孔。

  2. 使用工具 (D) ,将新的唇形密封 (9) 安装到壳体 (1) 中。

    注: 安装密封时使密封金属表面上的零件号朝向壳体。 确保唇形密封与壳体沉孔的前边缘平齐。 请勿润滑唇形密封。 使用压具安装唇形密封。 请勿用手安装唇形密封。

  3. 将轴承组件 (8) 安装在水泵轴 (6) 上。

  4. 安放护圈 (5),使 “OUTSIDE”(外侧)标记朝向水泵轴 (6) 的齿轮端。

  5. 利用压具将齿轮 (2) 安装到水泵轴 (6) 上。

    注: 安装齿轮 (2),使其紧贴轴承组件 (8)。

  6. 将工具 (E) 在轴 (6) 的上方滑动。 锥边缘将朝向外侧。

  7. 将齿轮 (2) 和水泵轴安装到壳体 (1) 中。 小心不要损坏唇形密封 (9)。 安装将轴承挡圈 (5) 固定在壳体上的螺栓 (3) 。

  8. 将工具 (E) 从水泵轴 (6) 上拆下。

  9. 利用压具和工具 (F) 将新密封总成 (7) 安装到轴 (6) 上和壳体 (1) 中。 确保密封外侧壳体完全座入壳体中。

  10. 将叶轮 (4) 在水泵轴 (6) 上放置到位。 利用压具将叶轮 (4) 安装到水泵轴上。

    注: 安装叶轮 (4) 时应距水泵轴端 0.00 ± 0.25 mm (0.000 ± 0.010 in) 以内。

  11. 将 O 形密封圈 (10) 安装在壳体上。

结束:

  1. 安装水泵。
